[FIX] point_of_sale: prevent removing order after bill screen timeout

steps to reproduce the issue:
-Navigate to POS, Open Bar (needs to be restaurant POS)
-Click on a table and add some items to the order.
-Click the Bill button under the order
-Wait about 90 seconds
-Bill page times out and goes back to the floor screen
-Click on Orders at the top and view Ongoing Orders. The one you just
made is not here (it should be)

The solution is to prevent removing the not finalized order when
coming back to the FloorScreen.
